Psychosis associated with dementia has recently been validated
as a specific syndrome. Knowledge about diagnosis, natural history,
and treatment response is evolving rapidly, and is being incorporated
into clinical recommendations.
Dr. Mintzer examined various behavioral disturbances associated
with dementia and identified those causing serious problems for
caregivers. In particular, Dr. Mintzer emphasized that agitation
may represent an inappropriate and problematic consequence of behaviors,
but may also result from various medical and situational factors.
Dr. Mintzer discussed a tentative treatment algorithm for behavioral
abnormalities in dementia. Agitation and aggressive behaviors may
improve following a change of environment, such as placement in
a behavioral intensive care unit or admission to full or partial
hospitalization.
Next, he outlined appropriate pharmacotherapeutic options, which
include cholinesterase inhibitors, antipsychotics, antidepressants,
anticonvulsants, and anti-anxiety agents. He discussed selection
of appropriate pharmacologic agents, dosages, durations of treatment,
and approaches to evaluating outcome.
Dr. Mintzer emphasized practical approaches to monitoring for adverse
effects and safety concerns, and also described strategies for managing
patients who do not respond to or cannot tolerate initial treatment.
He discussed the role of combination pharmacotherapy for some patients,
and illustrated his discussion with preliminary results of a study
of donepezil and risperidone co-administration.
The goals and strategies for managing dementia may differ as a
function of the context of care. However, Dr. Mintzer concluded
that supplementing pharmacologic treatment with behavioral, interpersonal,
and environmental approaches might prove beneficial for psychotic
patients with dementia.
